Abstract

The method involves operating a low-pressure cylinder (1) and two high-pressure cylinders (2, 3) following two and four stroke type modes respectively. An overall expansion ratio of an engine is increased by intervening a part of a cylinder capacity of the high-pressure cylinders in maximum expansion volume, without increasing the cylinder capacity of the engine, compression ratio of the high-pressure cylinders, dead volume (V3) of the low-pressure cylinder or volume of oxidized gas decanting channel from the high pressure cylinders to the low-pressure cylinder.
